Abstract [en]

Aim: This study aimed to evaluate the clinical utility of the Structured Observation of Motor Performance in Infants (SOMP-I) when used by nurses in routine child healthcare by analyzing the nurses' SOMP-I assessments and the actions taken when motor problems were suspected.

Method: Infants from three child health centers in Uppsala County, Sweden, were consecutively enrolled in a longitudinal study. The 242 infants were assessed using SOMP-I by the nurse responsible for the infant as part of the regular well-child visits at as close to 2, 4, 6 and 10 months of age as possible. The nurses noted actions taken such as giving advice, scheduling an extra follow-up or referring the infant to specialized care. The infants' motor development was reassessed at 18 months of age through review of medical records or parental report.

Results: The assessments of level of motor development at 2 and 10 months showed a distribution corresponding to the percentile distribution of the SOMP-I method. Fewer infants than expected were assessed as delayed at 4 and 6 months or deficient in quality at all assessment ages. When an infant was assessed as delayed in level or deficient in quality, the likelihood of the nurse taking actions increased. This increased further if both delay and quality deficit were found at the same assessment or if one or both were found at repeated assessments. The reassessment of the motor development at 18 months did not reveal any missed infants with major motor impairments.

Interpretation: The use of SOMP-I appears to demonstrate favorable clinical utility in routine child healthcare as tested here. Child health nurses can assess early motor performance using this standardized assessment method, and using the method appears to support them the clinical decision-making.

Abstract [en]

The Swedish child health services (CHS) have a unique position in that they reach almost all children 0-6 years of age. The child health nurse has the main responsibility for developmental surveillance. Twelve scheduled visits with the nurse during the child’s first year of life make this an ideal setting to systematically identify infants with motor problems, ranging from asymmetric head positioning that may lead to plagiocephaly to more severe forms such as cerebral palsy (CP). However, the CHS lack evidence-based methods to assess motor development.

The Structured Observation of Motor Performance in Infants (SOMP-I) assesses motor performance in two domains, i.e. level of motor development and quality of motor performance. SOMP-I is quick, non-invasive, requires minimal handling, and is suitable for a busy clinical setting when applied by physiotherapists. Given the importance of early detection, the increased likelihood of detecting motor problems when using evidence-based assessment methods and the key role of nurses within the CHS, the overall aim of this thesis was investigate the psychometric properties and clinical utility of SOMP-I when used by child health nurses. Furthermore, we aimed to establish the ability of SOMP-I to detect CP.

Our results show that child health nurses can reliably assess the level of motor development in infants using SOMP-I. More variability was found when they assessed the infants’ quality of motor performance. Although the nurses expressed concern about introducing a more time-consuming assessment in an already tight schedule, they were able to integrate the SOMP-I assessment in routine care. The nurses reported that barriers to using SOMP-I were mostly logistic and practical in nature, and they pointed out the necessity of education and practice in order to become proficient assessors. Using SOMP-I appears to have supported the nurses in the decision-making process regarding motor performance in routine care. SOMP-I detected CP during the first months of life in neonatal intensive care recipients.

To our knowledge, these studies are the first to evaluate child health nurses’ assessment of early motor performance using an evidence-based assessment method in routine care. The results are promising, but further research is warranted.
